You want something specific, so you'll need to write specific emacs
lisp code to implement it.

Beurk.  What'd look "pretty" for me would be:

     if((work[x][y]<expression[x][y])
      ||(work[x+1][y]<expression[x+1][y])
      ||(work[x][y+1]<expression[x][y+1])
      ||(work[x][y-1]<expression[x][y-1])){

See what I mean by "specific"...

So, you need to write (at least a partial) parser for C in emacs lisp,
matching C statements and expressions, and reformating them.
